| dc.description.abstract | Nanostructured semi-conductor materials based on titanium dioxide, with effective photo-catalytic properties under UV illumination, were synthesized using sol-gel technology and characterized by X-Ray diffraction and scanning electron microscopy, with the objective of studying the photo-catalytic hydrogen production from water. The need to decrease the electron-hole recombination rate was accounted for by metal doping and the addition of ethanol as a hole trap. Aqueous suspensions of the semiconductor powders, with noble metal loadings (Pt) of 1.5 wt% were used and the effect of solution pH and temperature (20-70ºC) on hydrogen production were studied, for a selected catalyst concentration. Hydrogen production rates were found to be linear with solution temperature with values larger than published literature data. | pt |
